Android - Intent back to current TabHost สอบถามปัญหาการส่ง หน้าคืนกลับมาที่ Activity ที่สองของ TabHost ครับ

protected void onCreate(Bundle savedInstanceState) {
		/*The exception that is thrown when an application attempts to perform a networking operation on its main thread. See StrictMode below*/
		//StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
		//StrictMode.setThreadPolicy(policy);
		/*-------------------------------------------------------------------------------------------------------------------------------------*/
		 super.onCreate(savedInstanceState);
		 setContentView(R.layout.tabmanu);
		
		 
		 Intent inboundIntent = getIntent();
		 String user_name = inboundIntent.getExtras().getString("username");
		 String n = user_name;
		 Log.d("userTab" ,n);
		 
		 Resources res = getResources();
			TabHost tabHost = this.getTabHost();
			TabHost.TabSpec spec;
			Intent intent;
			
			intent = new Intent().setClass(this.getApplicationContext(), Income.class);			
			Bundle bundle = new Bundle();
			bundle.putString("username", n); //SEND USERNAME FROM LOGIN PAGE TO NEXT LAYOUT PAGE
			intent.putExtras(bundle); 
			spec = tabHost.newTabSpec("Income").setIndicator("income").setContent(intent);
			tabHost.addTab(spec);
			
			intent = new Intent().setClass(this.getApplicationContext(), Expense.class);
			Bundle eBundle = new Bundle();
			eBundle.putString("username", n);
			intent.putExtras(eBundle);
			spec = tabHost.newTabSpec("Expense").setIndicator("expense",res.getDrawable(R.drawable.expense))
					.setContent(intent);
			tabHost.addTab(spec);
			
			intent = new Intent().setClass(this.getApplicationContext(), Reports.class);
			spec = tabHost.newTabSpec("REPORT").setIndicator("report").setContent(intent);
			tabHost.addTab(spec);
					
	} // End of onCreate Method

}
